A tripod head is the part of a tripod system that attaches the supported device (such as a camera) to the tripod legs, and allows the orientation of the device to be manipulated or locked down. Modular or stand-alone tripod heads can be used on a wide range of tripods, allowing the user to choose which type of head best suits their needs.
A ball head is a metal or plastic apparatus placed on top of a tripod that increases stability and provides faster, more accurate rotation of the camera for the photographer. They are lighter than traditional three-way pan-tilt tripod heads. [citation needed] With fewer parts and a much simpler mechanism, ball heads are usually preferred by ...
A ball head utilizes a ball joint to allow rotational movement about all axes from a single point. Some ball heads also have a separate panoramic rotation joint on the base of the head. The head has two main parts, the ball, which attaches to the camera, and the socket, which attaches to the tripod. The camera is attached to the ball by means ...
Robert Eric Miller, an Australian engineer from Sydney, invented the fluid head for motion picture cameras for which he was granted an Australian patent in 1946 and US patent in 1949. [5] He founded Miller Camera Support Equipment in 1954, manufacturing fluid heads and tripods. The same year, he developed the Miller Viscosity Drag.
In cinematography, a jib is any boom device used to mount a camera on one end, and a counterweight with camera controls on the other. [1] In principle, it operates like a see-saw, with the balance point located closer to the counterweight, which allows the end of the arm with the camera to move through an extended arc.
In the largest telescopes, the mass and cost of an equatorial mount is prohibitive and they have been superseded by computer-controlled altazimuth mounts. [5] The simple structure of an altazimuth mount allows significant cost reductions, in spite of the additional cost associated with the more complex tracking and image-orienting mechanisms. [6]
